This register indicates which PTD stored in the INTL buffer is currently active and is
updated by the host controller. The HCD can use it as a buffer pointer to decide which
PTD locations are currently free to fill in new PTDs to the buffer. This indication is to
prevent the HCD from accidentally writing into the currently active PTD buffer location.

This register allows you to allocate the size of the ATL buffer to be used for aperiodic
transactions. The default value of the buffer size is set to 512 bytes, and the maximum
allowable allocated size is 4096 bytes. The bit description of the register is given in

In addition to the HcDirectAddressData register, the ISP1362 provides this register to act
as another data port to access the ATL buffer. The starting address to access the buffer is
always fixed at 0000h. Therefore, random access of the ATL buffer is not allowed. The bit
